Metal nanoclusters (NCs) constitute a novel sector of metal nanomaterials with fascinating physicochemical properties by virtue of peculiar atomic stacking mode and quantum confinement effect, which are wholly distinct from conventional metal nanocrystals. Precise tuning of photo-induced charge carriers  over  atomically accurate metal NCs with quasi-semiconductor HOMO-LUMO gap would unleash novel  photosystems for solar energy conversion. However, there is significant deficiency of metal NCs-based photosystems with charge transfer mechanism remaining elusive owing to the scarcity of semiconductors with suitable band structures, ultra-short carrier lifetime  of metal NCs, and difficulty in regulating the charge flow of metal NCs.  Herein, we unleash the unanticipated charge transfer capability of non-conjugated polymer from the perspective of fundamental chemistry and demonstrate fine tuning of charge carriers of metal NCs by such a non-conductive polymer for crafting long-range tandem charge transfer chain.
